CAR-LOADING APPARATUS.

To all whom it may concern:

- .w-Be it known that LRAYuoNo G.LAWRY, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Car-Loading Apparatus, of which the following is aspecificasuch as coal, and has for one ofits objects to provide a newand improved means for conveying and loading lump and other larger sizesof coal into the cars without breaking.

It is illustrated diagrammatically in one form in the accompanyingdrawlng wherein- Figure 1 is a diagrammatic plan view of diagrammaticside elevation; Fig. 3 is a detail in plan of a portion of the feedingmachinery; Fig. 4 is a side elevation in part section of the parts shownin Fig. 3; Fig. 5

' Fig. 6 is a detail of the adjustable eccentric.

Like parts are indicated by like letters throughout the several figures.I

A- A are railroad tracks along which the coal cars shown-in dotted linesat A are adapted to travel.

A is a supporting frame work which carries a combined screen andconveyer chute A The chute A is mounted for reciprocation on the rollersA on the supporting framework A-,and is connected for reciprocation bymeans of the drive link A with any suitable source of reciprocatingpower. The combined screen and conveyer chute has bined screening andconveying deck along which coal or other suitable material is fed fromthe chute B toward the discharge end by the reciprocation of theconveyer.

The smooth conveying surfaces 13 of the conveyer deck are broken up atcertain points by a fine screen 13 a medium screen B and a coarse screenB the fine screen being at the upper end and the coarse screen adjacentthe lower end of the conveyer.

Beneath the deck B and supported between the side walls B is a lowerdeck B apertured at -B B and B below the lower boundarles of the screensB B and B These apertures discharge into the chutes B B and B which aremounted for discharge into the separate cars A The spout C forms acontinuation or discharge end for the conveyer chute A and is graduallyreduced in cross section downwardly toward the discharge point where itdischarges into an inclined chute D, which in my preferred form isarranged at right angles to the chute A The chute D is supported onrollers D which rollers ride upon the frame D and it is adapted to bereciprocated by the link D? having a strap D surrounding the eccentrlc DThe chute D is apertured or screened as at D in register with the funnelor chute D discharging into a spiral screw conveyer D D is a drive shaftwhich drives the eccentrio D to reciprocate the chute D and thus feedthe material forward down the inclined surface thereof as it isdeposited upon the upper extremity by the spout C. The chute g Ddischarges at its lower end into the upper end of the pivotally mountedchute E.

E is a roller supporting the upper end of the chute E free toreciprocate along the frame D.

E is a supporting connection applied to the outer end of the chute E forraising and lowering it by means of any suitable tackle not here shown.

E is an eccentricon the shaft D and E r is an eccentric cam rotatableabout the eccentric E and apertured as indicated to permit engagement ofthe pin or key E to hold the eccentric and eccentric cam in any suitableposition with respect one to the other and thus form a single adjustableeccentric whose eccentricity may be varied at the will of the operatorby a manipulation of the outer cajm.

E is a connecting rod having a strap Fl surrounding the eccentric cam Eand pivextends back beneath the chute A and discharges adjacent thedischarge end of the chute B. It passes beneath the chutes B, B, which.chutes are provided with fine screens F, F to permit the extraction offine material and it is returned to the fine material car into whichthechute B nor mally discharges.

Itwill be evident that although I have shown in my drawings an operativedevice, still many changes might be made both in size, shape andarrangement of parts without departing materially from the spirit of myinvention, and I wish, therefore, that my drawings be regarded as in asense diagrammatic;

The use and operation of my invention are as follows: WVhen cars are tobe loaded with the screened, separated or graded material, the coal, formy device is designed primarily for use with coal, is fed to the upperend of the combined screen and con veyer chute through the spout B 'Thereciprocation of the inclined chute tends to feed the coal down towardthe lower end, and as it is thus fed it passes over the screen's'in thebottom of the platform as indicated. The first very fine screen takesout only the've'ry'finest particles such as dust, slack, and the like,and that being small is permitted to drop freely into the car below. TheneXt screen takesout pea or nut coal,

' or' the like, and'it drops down through the chute across the steppedscreen, and this also being small, each particle may be allowed to fallfreely into the car without danger of undue breakage. The dust which wasnot extracted at the first screen, or which may have been subsequentlyformed by rubbing together of the particles, passes through the finescreen to the conveyer which conveys it back to the discharge pointabove'thefirst car. The remaining coal on the separator or conveyerpasses on, part of it, such as egg coal, passing through the coarsescreen. This size may be re-screened before'it goes toits car the sameas the pea or the nut coal. The remainder is dis chargedas lump from theend of the chute. This coal thus finds itself upon the inclinedreci'p'rocating' chute and is fed downwardly toWard' the discharge endgoing over the p erferation's in the bottom. These perforatiens permit adroppingput of the fine partieles: notpreviously removed or subsequently formed and these fine particles are conveyed or: discharged totheconveyer whichcarries them back to thefirst car. The coarsematerial,such as egg or coarse hemp coal, is'then discharged in a continuous,gradually" moving stream from the end of ith'e'inclined chute to thepivotally mounted chute E. In order that this material maynot be brokenup and pulverized so as to produce irregularly graded and unsatisfactorycar loads it isnecessary that it be gently and easily conveyed to thecar without an abrupt fall. The inclined shaking feed spout E does this.As thecaris first being loaded the chute will be lowered so that itapproaches the bottom of the car. As the coal piles up in the car it isneces sary to raise the chute a small amount at a time so that materialdischarging from the end of chute falls only a short distance.

It is evident that for different sizes of coal and under differentweather conditions or conditions of moisture and the like, the relationbetween the inclination of the chute and the amplitude of itsreciprocation will vary and it maybe necessary tochange'the stroke ofthe inclined chute and it therefore becomes necessary to permit theoperator, who alone knows the conditions by being on the ground at thetime, to make the neces sary changes in the feed, and this the opera--tor can conveniently do by changing the position of the chute and thusits angleof inclination, and also by changing the length of stroke bymoving thec'am around a cer tain. amount on the eccentric."

I claim:

1. Means for discharging" materialsan'd' the like comprising a chutehavingone end pivoted and held against vertical displace' direction, adischarge chute having its axis in the same vertical plane as, andpivoted at one end, immediately below the discharge end of the feedchute, separate means for reciprocating it in a horizontal plane, meansi for controlling such reciprocation and means for raising andlowering'the free end of the chute to vary its angle of inclinationwithout longitudinally displacing it.

3. Means for conveying and discharging fragmentary materials and thelike comprising an inclined feed chute and means for reciprocating it ina generally horizontal direction, a discharge chutehaving'itsaxis'in thesame vertical plane as, and' pivotedl at one end immediately below' thedischarge"'- end ofthefeed chute and separate'm'eans for reciprocatingit in a horizontal plane.

4-. Means for conveying and discharging fragmentary materials and thelike comprising aninclined feed chute and means for reciprocating it ina generally horizontal directlon, a discharge chute having 1ts axis 1nthe same vertlcal plane as, and pivoted at one'end immediately below thedischarge end of the feed chute, separate means for reciprocating it ina horizontal planeand means for raising and loweringthe free end of thechute to vary its angle of inclination without longitudinally displacingit.
